Living Structures

Some creatures are so large that they can only be described in terms of Structural Hitpoints. While rare, these Living Structures are very difficult to damage by normal means and usually present challenges that need to be bypassed rather than destroyed. When attacking a creature with Structural Hitpoints an attack roll typically must be made (as per the base function of the power, GM discretion), but the resulting damage dealt is equivalent to the Structural Damage dealt by the power.
